High-performance 30kVA / 24kW true online double-conversion 3-phase UPS with internal battery and digital signal processing (DSP) control.
Low Upstream Harmonics: Attains a low input THDi of < 8% naturally, eliminating the need to oversize line transformers or supply generators
Advanced Battery Care (ABC): Temperature-compensated charging and software testing reduce structural micro-ripple to prolong standard battery lifespans
Scalable Vector Management: Patented digital execution speeds up voltage adjustments during heavy phase imbalances
Flexible Comm Ports: Native build provides localized volt-free contacts, dual RS232 slots, and expansion room for ManageUPSNET SNMP routing
Remote Diagnosis Facility: Entirely compatible with LIFE2000 remote diagnostic maintenance arrays for early fault alerts
